i dont know what i am

Okay, so I used to get crushes on guys all the time and was like inlove with two of those guys last year, one I've always had major crush on and the other one I liked for the whole year. But recently I've been thinking I was a lesbian or at the very least bi but I don't want to be anything but straight. I used to masturbate but when I did it wasn't over a guy or girl it was over how good the feeling was and how good it felt for me. I tried to masturbate over a guy but I can't and I didn't try over a girl because I simply don't want too. Like I looked up pictures of naked woman men and didn't get aroused by either of them. I don't like looking at the pictures of naked women though its just ew. Not that I have a single problem with lesbian or bi's I just don't know who I am anymore. And like I can only ever orgasm when I think of the pleasure being done to me. I don't think I could ever date a girl or marry or have sex with one but I could with a guy. But now I'm just so confused about it and I've read like heaps of different peoples articles and stuff and people are saying you're a lesbian or you're bi and I just really don't want to be at all. I'm 14 btw and I've never had a crush on a girl before and don't think I will I just can't masturbate to a picture of a man. I don't know what to do? I don't know what I am or who I was or anything I'm questioning everything. I don't want to be this way at all, I don't want to be thinking like this or be a lesbian or be bi. Everyone is just saying its hormones but I don't know if it is? Everybody is like don't worry its not a big deal but to me it really is. Please help me what do you think?
